Britney Spears has sent a warning letter to her sister

The 'Toxic' hitmaker's legal team want the 'Zoey 101' actress to stop discussing the 40-year-old pop star's life and struggles when she's giving interviews to promote her new memoir, 'Things I Should Have Said', which they claimed features "misleading and outrageous claims" about Britney.

Britney's lawyer, Mathew Rosengart, wrote: "We write with some hesitation because the last thing Britney wants is to bring more attention to your ill-timed book and its misleading or outrageous claims about her.

""Although Britney has not read and does not intend to read your book, she and millions of her fans were shocked to see how you have exploited her for monetary gain. She will not tolerate it, nor should she."

After years under a conservatorship overseen by her father, Jamie Spears, the lawyer stressed Britney will not be "bullied" by anyone any more.

The letter continued: “You of all people know the abuse and wrongdoing Britney had to endure during the conservatorship, after initially growing up with a ‘ruinous,’ alcoholic father. In fact, your own book reportedly states that your father ‘spent most of my life in that cycle of ruinous behaviour. His bouts of drinking caused me periods of torment and sorrow.'

“As I have previously stated, having endured a 13-year conservatorship that stripped her of civil rights and fundamental liberties, Britney will no longer be bullied by her father or anyone else.”

Jamie Lynn was accused of “airing false or fantastical grievances” to garner publicity for her book and warned her sister will take further legal action if she continues to speak about her and their feud.

The letter concluded: “Britney was the family’s breadwinner and she also otherwise supported you. Publicly airing false or fantastical grievances is wrong, especially when designed to sell books. It is also potentially unlawful and defamatory.

“Michelle Obama famously said, ‘When they go low, we go high.' And to Britney’s great credit, that is exactly what Britney is going to do, for the time being.

“You recently reportedly stated that the book was ‘not about her.’ She takes you at your word and we, therefore, demand that you cease and desist from referencing Britney derogatorily during your promotional campaign.

"If you fail to do so or defame her, Britney will be forced to consider and take all appropriate legal action.”

The second part of Jamie Lynn's interview on the 'Call Her Daddy' podcast was due to be released on Wednesday (19.01.22) but it is currently unclear what will happen in the wake of the legal warning.
